You can use the AutoCAD UNDO command to undo the changes you made to an image.
However, for each image, only your last ten edits can be undone. This limit does not include display-only changes, such as changing the scale, rotation, or position of an image. There is no limit for undoing display-only changes.
The limit of ten edits applies to operations that change the image data, such as Rubbersheet, Remove, Crop, Histogram, using a vectorization tool with the REM setting, and so on.
